  Assaf Elovic / Tavily

  Autonomous AI agent that runs deep multi-source web research and writes cited reports.

  An open-source autonomous research agent that plans a task, runs parallel multi-source web searches, validates sources, and synthesizes a cited report. It runs locally as a Python package, FastAPI server, or MCP server, and works with any LLM provider plus a search/retriever backend. Free and Apache-2.0 licensed — you only pay your own LLM and search-API costs.

  AI insight: An open-source take on 'deep research' — it fans out parallel searches and cites sources, runnable as a library or an MCP server.

  Open-source AI second brain that chats with your docs and the web, local or hosted.

  An open-source "AI second brain" for chatting with local or online models, searching across your personal documents and the internet, building custom agents, and automating research. Self-host it on your own machine, or use plugins for Obsidian, Emacs, desktop, and mobile. Licensed AGPL-3.0; a paid managed cloud tier also exists, so it's freemium.

  AI insight: Lives inside the tools you already use — Obsidian, Emacs, desktop, mobile — as an AGPL second brain over your notes and the web.
